Cultris-Tetris-AI

This repo contains a preliminary attempt at creating a tetris AI to play the block-based puzzle game, Cultris 2 (available at http://gewaltig.net/cultris2.aspx). It uses a combination of internal game heuristics, particle swarm optimization and genetic algorithms to generate weight based and neural network based models to iterate through possible moves and play those that yield the best gamestates. Currently the AI has been well-trained to upstack, downstack, combo/attack and survive as long as possible in multiplayer and singleplayer modes.

Long Term To do:

Remove dependencies requrired for interfacing with Cultris
Make interfacing with Cultris cross-platform
Create evaluation functions/additional heuristics to train upstacking + comboing
Continue refactoring heuristic generation
Explore novel training methods and better NN structures

Short Term To do:

~~Integrate a simulated combo system that mimics Cultris~~ (Complete!)
~~Reduce board scoring iterations for redundant boards~~ (Complete!)
Create an autoencoder environment to generate training data for CNN training (in progress)
Integrate keras + tensorflow backend for CNN model creation
Create a self-play one vs one environment for the agents to train with
~~Fix matrix desync with Cultris due to sliding garbage detection issues (Complete!)~~

Installation

Create a virtualenv (recommended) and install the dependencies

$ cd cultris-tetris-ai
$ python3 -m venv . # recommended
$ source bin/activate
$ pip3 install -e . # setup.py contains a list of currently required dependencies

To run a test game:

$ python3 c2ai deap.pso.downstack 
# runs a simulated game in console using the weights in /deap/pso/downstack/tetris.py

Running the bot on Cultris 2 currently requires a specific environment (mac os, template matching, resolution and window sizing etc.) that is not transferable between PCs. This is on the to do list, however instructions are below for Mac OS on a 15 inch MBP:

# Set C2 dimensions to 1552 x 996. Use default piece orientations and colors.
# Controls: 
# C for Harddrop, Q for CCW rotation, W for Cw rotation, TAB for 180 rotation
# Arrow keys for L/R/Downwards Movement
$ cd c2ai
$ python3 main.py -x

Videos

Early videos of the AI's progress can be found below and will be updated infrequently. The AI is far more efficient now with the introduction of new heuristics, more training iterations, and bugfixes.
